Frequently Asked Questions
1.How many questions are in the MHTCET 2026 20th April Morning Shift paper?
This paper has 150 questions in total - 50 each from Chemistry, Mathematics, and Physics.
2.Can I practise questions from just one subject?
Yes. Use the Chemistry, Mathematics, and Physics tabs at the top of the page to jump directly to that subject's question set within this shift.
3.Is this the same paper for all students who appeared in the morning shift?
MHTCET uses different question sets across shifts and sessions to maintain exam integrity, so this page reflects the specific paper administered in the 20th April 2026 morning shift.
4.Where can I find the evening shift paper for the same date?
The MHTCET 2026 20th April Evening Shift paper is listed separately - you can switch to it from the "MHTCET Paper Wise PYQs" panel, under MHTCET 20th April 2026.
5.How is the MHTCET 2026 20th April Morning Shift paper structured?
The MHTCET 2026 20th April Morning Shift paper on MARKS has 150 questions, organised by subject:
- Chemistry: 50 questions - 50 single-correct.
- Mathematics: 50 questions - 50 single-correct.
- Physics: 50 questions - 50 single-correct.
6.How difficult is the MHTCET 2026 20th April Morning Shift paper?
Each question on MARKS carries a difficulty rating. Of the 150 rated questions in this paper, 61 (41%) are easy, 89 (59%) are medium and 0 (0%) are hard. Subject wise:

8.Where can I find the solutions for the MHTCET 2026 20th April Morning Shift paper?
Open any question on this page. Its page shows the correct answer and, where one is available, the worked solution. A downloadable PDF of the whole shift is coming soon.
9.How should I use the MHTCET 2026 20th April Morning Shift paper to check my preparation?
Set a timer, attempt the 150 questions as you would in the exam, and only then open the answers. Note which subjects and chapters cost you the most marks, and revise those first using the chapter-wise practice for MHTCET. Repeating this with other papers shows whether the same weak spots keep coming back.
10.Will the MHTCET 2026 20th April Morning Shift paper help me prepare for MHTCET 2027?
Yes. Every past paper shows the question styles and topics MHTCET has asked before, and a solved paper gives you a realistic benchmark for speed and accuracy. Use it along with the other papers to spot the chapters that keep returning.
